Install SynestheFox with Vimium.
Use the native find bar command+f to search for a word with colored text. Notice that vimium's has increased respnosiveness as compared to Orion.
The solution is not to include color in the factors when searching for text, and better optimization regarding separate words such as the span's which are color coded. It seems that vimium searches in a different manner which allows it greater efficiency in gigantic texts. For example, searching "the" in the command+f find bar will almost freeze the tab but searching "the" in vimium's '/' find bar found when pressing the slash key is much faster.
